Intelligent Message Routing And Delivery In A Telecommunications Network

ABSTRACT

Messages directed to a mobile device are selectively routed to message servers based upon the capabilities of a network to which the mobile device is connected. According to an illustrative method disclosed herein, a network connectivity server receives a network identifier from the mobile device, the network connectivity server receives a request for routing instructions for the message, and the network connectivity server determines if the network identified by the network identifier is capable of delivering the message. The network connectivity server then instructs the message server to route the message according to a standard delivery method for a message type of the message or to a message conversion server computer based upon the determination. The message conversion server computer converts the message into a new message type that the network is capable of delivering to the mobile device.

BACKGROUND

Mobile messaging is available through many different messaging technologies. From traditional voice mail messages, to short messaging service (“SMS”) messages, multimedia messing service (“MMS”) messages, email messages, instant messaging (“IM”) service messages, and social networking status messages, mobile device users are increasingly relying on multiple messaging technologies to communicate with their friends, families, and colleagues. To modern mobile device users, the difference between these message types should become blurred because the content of the message is often important to the user, not the method by which the message was delivered. However, due to the underlying technology differences used to route and deliver various messages, the availability of messages is often reliant upon the type of network to which a user's mobile device is connected, the condition of the connection, and potentially other factors, such as whether the mobile device is roaming. This may cause messages to be delayed, resulting in an unintelligible or out-of-date message being sent to the recipient. In some instances, the messages may not be delivered at all, such as when a SMS message is available for the mobile device, but the mobile device is only connected to a wireless local area network via WI-FI.

It is with respect to these and other considerations that the disclosure made herein is presented.

SUMMARY

Concepts and technologies are described herein for intelligent message routing and delivery in a telecommunications network. According to one aspect disclosed herein, a method for providing routing instructions to a message server for routing a message to a mobile device may include receiving a network identifier from the mobile device. The network identifier may identify a network to which the mobile device is connected. The method may further include receiving a request for routing instructions for the message, and determining if the network identified by the network identifier is capable of delivering the message. In some embodiments, the capability of the network may include the capability of the network for a particular subscriber, such as the subscriber being provisioned for voice service and not data service via the network, or vice versa. The method may further include instructing the message server to route the message according to a standard delivery method for a message type of the message, if it is determined that the network is capable of delivering the message. The method may further include instructing the message server to route the message to a message conversion server computer, if the network connectivity server computer determines that the network is not capable of delivering the message. The message conversion server computer may be configured to convert the message into a new message type that the network is capable of delivering to the mobile device.

The RAN 104 may be in communication with a core network 106, which may include a circuit-switched core network (“CS CN”), a packet-switched core network (“PS CN”), and/or an IP multimedia subsystem (“IMS”) core network. The core network 106 may utilize one or more mobile telecommunications technologies to provide voice and/or data services to the mobile device 102 via the RAN 104 to a WWAN component (not shown) of the mobile device 102. The mobile telecommunications technologies include, but are not limited to, GSM, Code Division Multiple Access (“CDMA”) ONE, CDMA2000, UMTS, LTE, Worldwide Interoperability for Microwave Access (“WiMAX”), other 802.XX technologies, and the like. Moreover, the RAN 104 may utilize various channel access methods (which may or may not be used by the aforementioned standards) including, but not limited to, Time Division Multiple Access (“TDMA”), Frequency Division Multiple Access (“FDMA”), CDMA, wideband CDMA (“W-CDMA”), Orthogonal Frequency Division Multiplexing (“OFDM”), Space Division Multiple Access (“SDMA”), and/or the like to provide access to the core network 106. Data communications may be provided using General Packet Radio Service (“GPRS”), Enhanced Data rates for Global Evolution (“EDGE”), the High-Speed Packet Access (“HSPA”) protocol family including High-Speed Downlink Packet Access (“HSDPA”), Enhanced Uplink (“EUL”) or otherwise termed High-Speed Uplink Packet Access (“HSUPA”), Evolved HSPA (“HSPA+”), LTE, and various other current and future wireless data access standards. The core network 106 may be configured to provide voice and/or data communications with any combination of the above technologies. The core network 106 may be configured to or adapted to provide voice and/or data communications in accordance with future generation technologies.

The core network 106 may be in communication with one or more circuit networks 108, such as a public switched telephone network (“PSTN”), an integrated services digital network (“ISDN”), or other circuit-switched network. The core network 106 may also be in communication with one or more packet networks 110, such as an internet, the Internet, an intranet, or other packet-switched network.

The packet-switched network(s) 110 may be in communication with an internet service provider (“ISP”) network 112, which may provide access to the packet network 110 for other packet-switched networks, such as a wireless local area network (“WLAN”) access network 114. In some embodiments, the WLAN access network 114 may be configured to operate in accordance with one or more Institute of Electrical and Electronic Engineers (“IEEE”) 802.11 standards, such as IEEE 802.11a, 802.11b, 802.11g, 802.11n, and/or future 802.11 standard (referred to herein collectively as WI-FI). Draft 802.11 standards are also contemplated. In some embodiments, the WLAN may be implemented utilizing one or more wireless WI-FI access points. In some embodiments, one or more of the wireless WI-FI access points are another computing device, such as a cellular telephone, smart phone, computer, or tablet, that is functioning as a WI-FI hotspot, and that has connectivity to a wireless wide area network (“WWAN”), such as provided by the RAN 104 and the core network 106. Connections to WLAN access network 114 may be secured via various encryption technologies including, but not limited to, WI-FI Protected Access (“WPA”), WPA2, Wired Equivalent Privacy (“WEP”), and the like.

The packet-switched network(s) 110 may also be in communication with one or more email servers 116, one or more instant messaging (“IM”) service servers 118, and one or more social networking (“SN”) servers 120. In some embodiments, the servers 116, 118, 120 may be implemented as respective servers or computing systems including at least one respective computer. However, in other embodiments, two or more of the servers 116, 118, 120 may be implemented as components of the same server or computing system, including a network or cloud-computing system. The email server 116, the IM service server 118, and the SN server 120 may be configured to communicate with the mobile device 102 over the packet network(s) 110 via a data connection facilitated by the RAN 104 and the core network 106, and/or the ISP network 112 and the WLAN access network 114.

The email server 116 may be configured to deliver email to/from the mobile device 102. In some embodiments, the email server 116 may be configured to utilize one or more email protocols such as, but not limited to, post office protocol (“POP”), Internet mail access protocol (“IMAP”), simple mail transfer protocol (“SMTP”), hypertext transfer protocol (“HTTP”), or some combination thereof, to deliver email to and receive email from the mobile device 102. The email server 116 may also be configured to receive email messages that have been converted from another message type for delivery to the mobile device 102, as will be described in greater detail below.

The IM service server 118 may be configured to deliver an IM service via which a user of the mobile device 102 and one or more people can engage in a communication session to exchange text, images, voice, and/or video. In some embodiments, the IM service server 118 may be configured to utilize one or more IM protocols such as, but not limited, to Internet relay chat (“IRC”), Microsoft Messenger, available from MICROSOFT CORPORTATION, Windows Live Messenger, also available from MICROSOFT CORPORTATION, OSCAR, available from AOL, Skype protocol, available from Skype, available from MICROSOFT CORPORATION, Yahoo! Messenger, available from YAHOO, extensible messaging and presence protocol (“XMPP”), Facebook Messenger, available from FACEBOOK CORPORATION, or some combination thereof, to deliver instant messages to and receive instant messages from the mobile device 102. The IM service server 118 is also configured to receive IM messages that have been converted from another message type for delivery to the mobile device 102, as will be described in greater detail below.

The SN server 120 may be configured to deliver social networking messages to/from the mobile device 102. Social networking messages may include, but are not limited to, social networking status messages, social networking chat messages, social networking update messages, or some combination thereof. In some embodiments, the SN server 120 utilizes the email server 116 and/or the IM service server 118, and/or a similar server or computer to provide certain functionality for a social networking messaging infrastructure. For example, a social networking chat may utilize services provided by the IM service server 118 or a similar server integrated within the SN server 120. The SN server 120 is also configured to receive social networking messages that have been converted from another message type for delivery to the mobile device 102, as will be described in greater detail below.

It should be understood that the messages described herein may include content in the form of audio, video, text, image, and/or some combination thereof. It also should be understood that the messages may include an attachment including one or more of audio, video, text, image, and/or some combination thereof.

The core network 106 may also be in communication with a short messaging service center (“SMS-C”) and a multimedia messaging service center (“MMS-C”), illustrated as a combined SMS-C/MMS-C 122. The SMS-C and the MMS-C may be the same network entity or respective separate network entities within the operating environment 100. The SMS-C/MMS-C 122 may be configured to deliver SMS and/or MMS messages to the mobile device 102. The SMS-C/MMS-C 122 may also be configured to receive SMS and/or MMS messages that have been converted from another message type for delivery to the mobile device 102, as will be described in greater detail below.

The core network 106 may also be in communication with a network connectivity server 124. The network connectivity server 124 may be configured to receive network identifiers from the mobile device 102 indicating to which network the mobile device 102 is connected. When the mobile device 102 is connected to a network, such as the RAN 104 or the WLAN access network 114, a client application 126 executing on the mobile device 102 may generate a network identifier and sends the network identifier to the network connectivity server 124 to identify the network to which the mobile device 102 is connected. Various network identifiers are described in greater detail below. In some embodiments, the network to which the mobile device 102 is connected provides a service, such as a data service, but the user of the mobile device 102 is not subscribed to that service or is otherwise not provisioned to utilize that service. Accordingly, in these embodiments, the network identifier may identify a network with an indication that only a portion of the capabilities (e.g., voice-only or data-only) of that network are available to the mobile device 102. A method for operating the mobile device 102 to provide a network identifier to the network connectivity server 124 is illustrated and described with reference to FIG. 2. A method for operating the network connectivity server 124 is illustrated and described with reference to FIG. 3.

In some embodiments, the network connectivity server 124 may be a presence server that is configured to store to maintain presence information for subscribers within a mobile telecommunications network. In an illustrative embodiment, the term “presence” may refer to the availability, activity level, or operating state of a mobile device and/or a user associated therewith. The ability for users to monitor each other's presence may be a feature offered in connection with some messaging applications, such as instant messaging application, social networking chat applications, and the like. For example, some messaging applications have a buddy list or contact list feature that displays a contact list and a presence status for each contact in the list. The presence status may indicate a user's availability and/or current activity so that others can determine whether to send a message to a particular contact. A presence status can include, but is not limited to, available, unavailable, do not disturb, idle, busy, offline or a custom status. Presence information may include a network identifier, or a network identifier may be provided in addition to presence information.

The core network 106 may also be in communication with a message transcoding/translation server 128. In some embodiments, the message transcoding/translation server 128 may be configured to convert one or more message types to one more different message types. For example, the message transcoding/translation server 128 may be configured to convert an email message received from the email server 116 into a SMS message and deliver the SMS message to the SMS-C/MMS-C 122 for delivery to the mobile device 102. The conversion process may utilize one or more translation and/or transcoding techniques to convert a message from one type to another. In some embodiments, speech-to-text or text-to-speech conversion may be utilized in the conversion. In some embodiments, short-hand or other abbreviated language may be used in character-limited message types, such as SMS. Example methods for operating the message transcoding/translation server 128 are illustrated and described with reference to FIGS. 5 and 6.

The core network 106 may also be in communication with a home location register (“HLR”) and a home subscriber server (“HSS”), illustrated as a combined HLR/HSS 130. The HLR/HSS 130 may be shown as a combined network element for convenience and ease of illustration, although the HLR and the HSS may be separate network elements, according to an illustrative embodiment. The HLR/HSS 130 may include a database configured to provide routing information for mobile terminated calls and various messaging communications. In some embodiments, the HLR/HSS 130 includes a computer configured to support the HLR/HSS database functionality described herein. The HLR/HSS 130 may also be configured to maintain subscriber data that is distributed to the relevant visitor location register (“VLR”) (not shown) or serving general packet radio service support node (“SGSN”) (also not shown) through an attach process and to provide mobility management procedures, such as location area and routing area updates.

In some embodiments, the core network 106 is or includes an IMS network, as described above. The IMS network may include the HSS portion of the HLR/HSS 130. The HSS may be a master user database that stores subscription-related information, such as subscriber account details and subscriber profiles, performs authentication and authorization of the user, and provides information about a subscriber's location and IP address. In general, the HSS performs similar functions for an IMS network that an HLR provides for GSM and UMTS-based networks.

The core network 106 may also facilitate communication with one or more other public land mobile networks (“PLMNs”) 132. The other PLMN 132 may be, for example, a foreign network, such as a mobile telecommunications network operated by another service provider or the same service provider that operates the core network 106. In some embodiments, the mobile device 102 may be configured to access voice and/or data services while roaming on the other PLMN 132. In some embodiments, the mobile device 102 may be roaming on the other PLMN 132, but only has access to circuit-switched based services such as making and receiving voice calls, receiving voice mail waiting indications, retrieving voice mail, and sending and receiving SMS messages. However, due to contractual agreements between the service provider of the core network 106 and the service provider of the other PLMN 132, or for some other reason, the mobile device 102 may lack packet-switched based services such as MMS, IM, and email while roaming on the other PLMN 132. In these embodiments, an incoming packet-based message can be converted at the message transcoding/translation server 128 into an SMS or other message type that is available to the mobile device 102 via the other PLMN 132.

Turning now to FIG. 2, a flow diagram illustrating aspects of method 200 performed by the mobile device 102 for notifying the network connectivity server 124 of a network to which the mobile device 102 is connected via a network identifier will be described, according to an illustrative embodiment. It should be understood that the operations of the illustrative methods disclosed herein are not necessarily presented in any particular order and that performance of some or all of the operations in an alternative order(s) is possible and is contemplated. The operations have been presented in the demonstrated order for ease of description and illustration. Operations may be added, omitted, and/or performed simultaneously, at least in part, without departing from the scope of the appended claims.

It also should be understood that the illustrated methods can be ended at any time and need not be performed in its entirety. Some or all operations of the methods, and/or substantially equivalent operations, can be performed by execution of computer-readable instructions included on a computer-storage media, as defined below. The term “computer-readable instructions,” and variants thereof, as used in the description and claims, is used expansively herein to include routines, applications, software, application modules, program modules, programs, components, data structures, algorithms, and the like. Computer-readable instructions can be implemented on various system configurations, including single-processor or multiprocessor systems, distributed computing systems, minicomputers, mainframe computers, personal computers, hand-held computing devices, microprocessor-based, programmable consumer electronics, combinations thereof, and the like.

Thus, it should be appreciated that the logical operations described herein may be implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as states, operations, structural devices, acts, or modules. These operations, structural devices, acts, and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof.

The method 200 begins and proceeds to operation 202, wherein the mobile device 102 may connect to a network through the RAN 104, the WLAN access network 114, or another access network. In response to establishing a connection to the network, the client application 126 executing on the mobile device 102 determines a network identifier associated with the network. For embodiments in which the network is the RAN 104 or the like, the client application 126 may determine a network identifier that identifies the network as being an IP packet data network, a voice network, or a combination thereof. This may be determined at least in part by the client application 126 analyzing one or more connection settings established on the mobile device 102. The connection settings include, but are not limited to, an access point name (“APN”) identifying a packet data network to which the RAN 104 provides access, a network address for a proxy server to which the mobile device 102 is connected via the network to provide a service such as MMS messaging via the SMS-C/MMS-C 122, a network name, a network provider name, a cell identifier (“cell ID”) for a cell to which the mobile device 102 is connected, a location area identifier (“LAI”), or a combination thereof. In some embodiments, the absence of one or more connection settings, such as a setting that indicates a data connection is available, facilitates the client application 126 to determine that a data connection is not available. The corresponding network identifier may indicate a voice-only network.

For embodiments in which the network is the WLAN access network 114, the client application 126 executing on the mobile device 102 may determine a network identifier that identifies the network via a network name, a service set identifier (“SSID”), an ISP name, an IP address, or some combination thereof. This may be determined at least in part by the client application 126 analyzing WI-FI connection settings established on the mobile device.

From operation 204, the method 200 proceeds to operation 206, wherein the mobile device 102 may send the network identifier to the network connectivity server 114. From operation 206, the method 200 proceeds to operation 208, wherein the mobile device 102 may receive an incoming message via the network. The type of incoming message may be based, at least in part, upon the capability of the network to deliver the incoming message to the mobile device 102, as will be described in greater detail below. The method 200 then proceeds to operation 208. The method 200 ends at operation 208.

Turning now to FIG. 3, a flow diagram illustrating aspects of a method 300 for a method 300 performed by the network connectivity server 124 for providing routing instructions to a message server instructing the message server to route an incoming message via a standard delivery method or to route the message to the message transcoding/translation server 128 based upon the network identifier received from the mobile device 102 will be described, according to an illustrative embodiment. The message server to which the network connectivity server 124 provides instructions may be the email server 126, the IM server 118, the SN server, the SMS-C/MMS-C 122, or some other server or network element configured to provide a messaging capability to the network. For example, the message server may be a traditional voice mail system or a visual voice mail system.

The method 300 begins and proceeds to operation 302, wherein the network connectivity server 124 receives the network identifier from the mobile device 102. In response to receiving the network identifier from the mobile device 102, the network connectivity server 124, at operation 304, updates a profile for a subscriber associated with the mobile device 102 to include the network identifier. If a profile is not available for the subscriber, the network connectivity server 124 can create a profile at this time and include the network identifier in the profile. The profile stored by the network connectivity server 124, in some embodiments, may be updated to include information received from other network elements, such as the HLR/HSS 130 in regard to network connectivity information. In some embodiments, the network identifier provided by the mobile device 102 may supersede any indication of a particular network to which the mobile device 102 is connected as identified by the HLR/HSS 130 or other network element.

From operation 304, the method 300 proceeds to operation 306, wherein the network connectivity server 124 may receive a query from a message server. The message server may be the SMS-C/MMS-C 112, the email server 124, the IM server 126, the social networking server 128, a voice mail server, or another message server. The query may include a request for routing instructions for an incoming message, which includes the mobile device 102 as the intended recipient device.

From operation 306, the method 300 proceeds to operation 308, wherein the network connectivity server 124 may determine if the mobile device 102 is connected to a network that is capable of delivering the incoming message to the mobile device 102. In some embodiments, the determination of whether the network is capable of delivering the incoming message may be a determination based upon a technical limitation of the network. For example, if the network is a circuit-switched network, the network may be considered to be incapable of delivering messages to the mobile device 102 that require a packet-switched network for delivery. By way of additional example, if the incoming message is an SMS message and the network identifier identifies the mobile device 102 as being connected to a WLAN, the network connectivity server 124 may determine that the network is considered to be incapable of delivering the incoming message to the mobile device 102. By way of contrasting example, if the incoming message is an email message and the network identifier identifies the mobile device 102 as being connected to a WLAN or to another network that supports data, the network connectivity server 114 may determine that the network is capable of delivering the incoming message to the mobile device 102.

In some embodiments, the determination of whether the network is capable of delivering the incoming message may be a determination based upon a capability of the network for a particular network subscriber. For example, if the subscriber associated with the mobile device 102 only has a voice and SMS subscription, the network may be considered to be incapable of delivering messages to the mobile device 102 that require a data connection for that subscriber. In some embodiments, the determination of whether the network is capable of delivering the incoming message may be based upon a subscriber preference. For example, if the subscriber has set a subscriber preference to utilize a WI-FI network instead of a cellular network for incoming messages, the network may be considered to be incapable of delivering cellular based messages, such as SMS or MMS, to the mobile device 102 for that subscriber based upon the subscriber preference.

In some embodiments, the mobile device 102 is a dual-mode mobile device configured to establish simultaneous connections to a WI-FI network and a cellular network. In some embodiments, the mobile device 102 is connected to a WI-FI network and cellular network access is disabled, or vice versa. In some embodiments, the mobile device 102 is registered in both a WI-FI network and a cellular network. In some embodiments, the determination of whether the network is capable of delivering the incoming message is based upon a subscriber connected network capability. For example, if the mobile device 102 is connected to a WI-FI network instead of a cellular network, the network is considered to be incapable of delivering cellular based messages, such as SMS or MMS, to the mobile device 102 for that subscriber.

If the network connectivity server 124 determines, at operation 308, that the mobile device is connected to a network that is capable of delivering the incoming message, the method 300 proceeds from operation 308 to operation 310, wherein the network connectivity server 124 may instruct the message server to route the incoming message to the mobile device 102 according to the standard delivery method for the incoming message. For example, if the incoming message is an email message, the email server 116 may send the incoming message to the mobile device 102 utilizing an email protocol such as, but not limited to, POP or IMAP. Similarly, if the message is an SMS message, for example, the message may be delivered via SMS protocol. In any case, the method 300 then proceeds to operation 312. The method 300 ends at operation 312.

If the network connectivity server 124 determines, at operation 308, that the mobile device 102 is not connected to a network that is capable of delivering the incoming message, the method 300 proceeds from operation 308 to operation 314, wherein the network connectivity server 124 may instruct the message server to route the message to the message transcoding/translation server 128. The method 300 then proceeds to operation 312, wherein the method 300 ends.

Turning now to FIG. 4, a flow diagram illustrating aspects of a method 400 performed by a message server for querying the network connectivity server 114 for routing instructions and routing an incoming message via a standard delivery method or to the message transcoding/translation server 128 based upon the routing instructions will be described, according to an illustrative embodiment. The method 400 begins and proceeds to operation 402, wherein the message server receives the incoming message directed to the mobile device 102. The message server may be the SMS-C/MMS-C 112, the email server 124, the IM server 126, the social networking server 128, a voice mail server, or another message server.

From operation 402, the method 400 proceeds to operation 404, wherein the message server may query the network connectivity server 124 for routing instructions. From operation 404, the method 400 proceeds to operation 406, wherein the message server receives routing instructions from the network connectivity server 124.
